Description

Technical Field

[0001] The present invention belongs to the technical field of high-speed train vibration reduction, and particularly relates to a detachable lateral stop with adjustable performance, which is used to limit excessive lateral displacement of the car body to improve the safety and operation stability of the train and enhance the riding experience of passengers. This lateral stop is widely used in the vibration reduction systems of trains in railway, urban rail and other systems, and is particularly suitable for high-speed trains with high requirements for vibration reduction performance and structural anti-detachment design. Background Art

[0002] The function of the lateral stop is to limit excessive lateral displacement of the car body relative to the bogie when the vehicle is running straight and passing through curves, so as to meet the line clearance requirements. A lateral stop is provided between the bogie frame and the car body. The lateral stop is a component of the suspension system and acts together with other secondary suspension components to buffer the lateral force between the car body and the bogie, which plays an important role in the safe operation of the train. Currently, the widely used lateral stops are formed by vulcanizing metal and rubber together. This lateral stop has the characteristics of simple structure and non-adjustable stiffness. However, for the laterally vulcanized stop, when the bonding fails, the rubber body will fall off from the base, resulting in the failure of the buffering function. Due to production, storage and transportation reasons, the bonding of individual lateral stops may fail, and they may fall off during train operation, affecting the safe operation of the train. Therefore, there is an urgent need to invent a detachable lateral stop with adjustable performance, which can not only adjust the stiffness, but also prevent component failure caused by the rubber body falling off, so as to ensure the safety and stability of the train system. Summary of the Invention

[0003] The purpose of the present invention is to: through the innovative design of the lateral stop base and the cooperation with the performance adjustment block, reduce the risk of the rubber body of the lateral stop falling off and improve the stiffness performance of the lateral stop, aiming to provide a detachable lateral stop with adjustable performance, which can prevent the rubber body from falling off due to bonding failure of the lateral stop, improve the service performance of the lateral stop and the safety of train operation, and can extend the service life of components and reduce the maintenance cost through structured design.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0005] A performance-adjustable anti-disconnection lateral stop, comprising a wear-resistant plate, a rubber body, a limit base, a performance adjustment block and a positioning pin. The wear-resistant plate is located at the top of the lateral stop and is in direct contact with the car body part. The wear-resistant plate is made of high molecular polyurethane material or engineering plastic, and has excellent vibration damping, wear resistance and anti-fatigue performance, and can effectively absorb and buffer the dynamic load transmitted from the car body to the bogie during the train operation. The wear-resistant plate adopts a circular boss design, and the circular boss adopts an integrated design, which can withstand the impact load from the car body and is beneficial to the load transfer to the limit base. The wear-resistant plate is fitted with the rubber body and is installed by an integral vulcanization process, which has the characteristics of good integrity and not easy to deform. The rubber body is located in the middle of the lateral stop and can transmit and absorb part of the energy from the car body collision. The rubber body material is high-elastic rubber, which has the characteristics of large deformation and high elasticity, and shows good vibration damping and buffering performance. The connection part between the surface of the rubber body and the limit base has an annular limit ring, and the size and number of turns of the limit ring are designed according to the installation requirements of the limit base to ensure the stable cooperation between the two parts. The existence of the limit ring can ensure the close cooperation between the rubber body and the limit base, prevent the possibility of the rubber body part falling off the base under the action of long-term load, and ensure the long-term stable operation of the lateral stop. The connection part between the inside of the rubber body and the positioning pin has an annular limit groove design, and the size and number of grooves of the annular limit groove are designed according to the shape and size requirements of the positioning pin to ensure the mutual cooperation between the performance adjustment block and the rubber body, prevent the performance adjustment block and the rubber body from shifting due to external force or vibration, thereby improving the stability and safety of the device, and ensuring that the performance adjustment block cooperates with the rubber body to play a vibration damping and energy absorption role. The limit base is a key component in the present invention, which not only limits the rubber body, but also is a key component for connecting the lateral stop and the bogie. The limit base is made of wear-resistant materials such as alloy steel to ensure that excessive deformation or wear does not occur during use. At the same time, the shape and size of the stop body can be customized according to different application requirements to meet the installation and use requirements of different high-speed train vibration damping systems. Both ends of the limit base have mounting holes, and are aligned and installed with the reserved positions on the bogie through bolts and anti-slip washers. The matching type between the limit base and the surface of the rubber body is an interference fit. Through the design of the guiding inclined plane and the annular limit groove, the guiding inclined plane can ensure the correct position of the stop body during the installation process, prevent the rubber body from shifting due to external force or vibration, thereby improving the stability and safety of the device. The role of the annular limit groove is to further ensure that the rubber body does not shift under high-intensity impact, can effectively limit the vertical or horizontal sliding of the rubber body, and reduce the possibility of the rubber body falling off the base from the structural design, and reduce the possibility of train operation accidents. A through hole is provided at the center of the bottom of the limit base, and its size is the same as the maximum diameter of the rubber body and the positioning pin, which is convenient for the installation of the two components. It ensures the tight connection at the joint between the base and the rubber body and the positioning pin, and ensures that the performance adjustment block cooperates with the rubber body to play a vibration damping role.The performance adjustment block is a key component for achieving adjustable vibration reduction performance of the lateral stop. The performance adjustment block is made of new materials such as polyurethane, which has the characteristics of light weight, excellent elasticity, oil resistance, corrosion resistance, and aging resistance. A thread is provided at the bottom of the performance adjustment block, which is connected to the central threaded hole of the positioning pin, and has the characteristics of stable installation and easy disassembly. By replacing different performance adjustment blocks, the stiffness of the lateral stop can be adjusted, which can be applied to lines with different operating conditions. In addition, the performance adjustment block is reliable in long-term use, which can extend the service life of the performance adjustment block and the lateral stop, reduce the maintenance cost of the train, and improve the overall operation efficiency and safety of the rail transit system. The positioning pin adopts a boss design, and the central threaded hole can be connected with the performance adjustment block. The positioning pin is made of polyurethane or high-density engineering plastics, which has the characteristics of high wear resistance, excellent elasticity, oil resistance, aging resistance, and adjustable hardness. The positioning pin ensures the stable connection relationship between the performance adjustment block, the rubber body, and the limit base. In summary, the performance-adjustable anti-slip lateral stop has the characteristics of simple structure, convenience and reliability, and is convenient for subsequent promotion.

Detailed Description of the Invention

[0031] The present invention will be further described in detail below in combination with test examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention belong to the scope of the present invention.

[0032] In the related art, during the use of the existing lateral stop, the rubber body and the base generally adopt an integrated vulcanization installation process, and the vibration reduction effect mainly depends on the performance of the rubber body material. This design does not fully consider the situation that the rubber body will fall off due to rubber aging or abnormal loading after the vehicle is installed. It does not have an anti-falling function and the vibration reduction effect is single. In addition, the existing maintenance requirements stipulate that the lateral stop must be replaced as a whole, but the base is still within the prescribed service life at the same time. The overall replacement will also cause a waste of resources and is not conducive to the company's cost control. The present invention proposes a performance-adjustable anti-falling lateral stop technical solution, which redesigns the shape of the rubber body and the base, and realizes the anti-falling function of the lateral stop rubber body through the design of guide bevels, limit rings, limit grooves, positioning pins, etc. The performance adjustment block is innovatively added to the inside of the rubber body. This design improves the rubber vibration suppression effect when the lateral stop is subjected to high loads. At the same time, through the selection of different damping block materials and structural optimization, the present invention has significant advantages in improving bearing capacity, vibration suppression and noise reduction, and significantly extends the service life of the lateral stop. The following will be combined with Figures 1 to 7 The structural features and advantages of the present invention are described in detail.

[0033] Example 1

[0034] like Figures 1 to 7As shown in the figure, the application solution under the standard train operation conditions is adopted in this embodiment. First, an anti - detachment type lateral stop with adjustable performance of the present invention is installed at the connection between the train bogie and the car body through bolts. The wear - resistant plate (1) body is made of high - density engineering plastics, which has excellent elasticity and wear resistance, and can effectively resist deformation and damage under high - load and dynamic - load conditions. The contact part between the wear - resistant plate (1) and the rubber body (2) is integrally formed by vulcanization process to ensure the overall pressure - bearing performance; at the contact part between the rubber body (2) and the outer surface of the limit base (3), there is a design of an annular limit ring (201), which can accurately contact the annular limit groove (301) and the guiding inclined plane (302) in the limit base (3), ensuring that the rubber body will not slide vertically or horizontally, so that the lateral stop has the anti - detachment function; the annular limit groove (301) and the guiding inclined plane (302) provided in the limit base (3) enable the lower surface of the rubber body (2) to be precisely installed therein, replacing the vulcanization installation process with a physical structure installation method; the performance adjustment block (4) is installed in the inner cavity of the rubber body (2) and is connected to the central threaded hole of the positioning pin (5) through the bottom thread. This innovative design of the performance adjustment block (4) can improve the vibration - damping performance of the lateral stop. By installing damping blocks with different material properties, the vibration - damping performance of the lateral stop can be adjusted. It can be adapted to the installation and use of high - speed trains in different regions and different line conditions. Considering that in the actual operation of the train, the rubber body (2) will age under the action of environmental factors, which may lead to component failure, and the addition of the performance adjustment block (4) can improve the stiffness of the lateral stop and ensure the long - term stable operation of the components. The positioning pin (5) body is made of high - density engineering plastics, which has excellent elasticity and wear resistance. Its top has a central threaded hole to achieve a stable connection with the performance adjustment block (4). Its side contacts the annular limit groove (202) inside the rubber body (2), which not only increases the contact area, restricts the sliding of the performance adjustment block, improves the integrity of the lateral stop, but also better transmits the load.

[0035] In summary, for the anti - detachment type lateral stop with adjustable performance described in this embodiment, by fixing the rubber body (2) in the limit base (3), and at the same time, cooperating the performance adjustment block (4) and the positioning pin (5) with the rubber body (2), the problem that components cannot be prevented from falling off in the traditional technology is solved, and the vibration - damping performance of the lateral stop is improved. The overall design is simple, which is convenient for production and installation, and can be widely applied to high - speed railway trains to ensure the safety and stability of train operation.

[0036] Embodiment 2

[0037] This embodiment provides a performance-adjustable anti-slip lateral stopper, which can be used in heavy-load trains to improve the shock absorption and vibration isolation performance of heavy-load trains during operation. The wear-resistant plate (1) in the lateral stopper is made of high-strength composite material, combining the excellent properties of materials such as rubber and polyurethane, and can effectively resist deformation and fatigue under high-load conditions, ensuring the safety and stability of the track system.

[0038] In this embodiment, the design of the rubber body (2) includes an annular limiting ring (201) and an annular limiting groove (202), which not only reduces the overall weight, but also achieves uniform stress distribution when subjected to force, thereby reducing damage caused by excessive local stress, thereby ensuring that when a heavy-load train body collides, it can effectively absorb and alleviate vibration and impact caused by dynamic loads.

[0039] The lateral stopper of this embodiment uses an integrated limit base (3), which can limit the movement of the rubber body, prevent the rubber body from falling off, which is a safety hazard, and reduce maintenance costs. The surface of the limit base (3) has been treated with corrosion resistance and has oil resistance. It can operate stably in harsh railway environments and ensure the performance of the components.

[0040] In addition, the performance adjustment block (4) is in contact with the rubber body (2), which can improve the lateral stop vibration reduction performance. According to different strength requirements, maintenance and adjustment can be performed as needed in the later stage to improve the service life of the components. In order to enhance the convenience of installation, the performance adjustment block (4) of this embodiment adopts a modular design so that it can quickly adapt to different types of vehicle bodies. Its waterproof and dustproof properties ensure that the elastic pad always maintains good performance in a complex railway environment, reduces the maintenance frequency, and improves the efficiency of railway operations.

[0041] In summary, the performance-adjustable anti-drop-type transverse stopper of Example 2 meets the high requirements of heavy-duty railways for shock absorption and vibration isolation through the application of high-performance materials, an anti-drop-functional base, and a replaceable performance adjustment block. This innovative design not only improves the safety and operational stability of railway tracks, but also provides strong support for the intelligent and efficient management of railway operations, and promotes the development and progress of the railway transportation industry.

[0042] Example 3

[0043] This embodiment provides an anti-slip lateral stop with adjustable performance, which is specially designed for plateau railways. The wear-resistant plate (1) is made of high-strength polyurethane material, which has excellent weather resistance, anti-aging and wear resistance. It can effectively operate stably in typical plateau environments such as low temperature, strong ultraviolet rays, high ozone concentration, and large temperature differences. It can effectively resist deformation and fatigue under high load conditions, ensuring the safety and stability of the high-speed train body system.

[0044] The outer surface of the rubber body (2) in this embodiment is designed with a limiting ring (201), which can be used in cooperation with the annular limiting groove (301) on the inner surface of the limiting base (3). Considering that the lateral stop serves on the vehicle bogie for a long time and is affected by environmental factors such as temperature change, ozone, and ultraviolet radiation, resulting in the aging of the rubber body. The traditional design uses vulcanization technology, and there is a risk of falling off after long-term use. The mating connection between the rubber body (2) and the limiting base (3) described in this case can achieve the function of preventing the rubber body from falling off, reduce the occurrence of operational safety accidents, and improve the running stability of the train.

[0045] For the convenience of installation and replacement, each component of the lateral stop in this embodiment adopts a modular design, enabling it to quickly adapt to the requirements of different vehicle types and configurations. Its waterproof and corrosion-resistant characteristics ensure that it can still operate normally under harsh driving conditions and extend its service life.

[0046] In summary, the performance-adjustable anti-detachment lateral stop of Embodiment 3, through the selection of high-performance materials and the integrated high-strength limiting base design, not only meets the stringent requirements of plateau railways for the aging performance of materials, but also improves the vibration damping performance of the train and the riding comfort of passengers. This innovative design provides strong support for the dynamic performance optimization and safety management of plateau railway operations, and helps the plateau railway to develop in the direction of high performance and greenness.

The performance-adjustable anti-detachment lateral stop is specially designed for urban rail transit systems, meeting the requirements of frequent train operations and high passenger flow in urban rail transit, and ensuring the safety, comfort, and economy of the system.

[0049] The wear-resistant plate (1) in this embodiment adopts a high-performance polyurethane material, which not only has good elasticity, but also has excellent anti-aging, wear-resistant, and weather-resistant properties, and can effectively cope with various complex conditions in the urban environment. It can meet the special requirements of urban rail transit and ensure the safety and comfort of passengers.

[0050] In addition, the structure of the rubber body (2) in this embodiment is optimized in design, enhancing its performance in absorbing vibration and shock. This structural design not only reduces the self-weight of the lateral stop, but also improves its overall stiffness and stability, ensuring that the lateral stop can evenly distribute and bear loads during the high-frequency train operations of urban rail transit, and reducing the lateral vibration of the car body.

[0051] In terms of noise control, the performance adjustment block (4) in this embodiment incorporates the application of acoustic materials, enabling the horizontal stop to effectively reduce the noise generated during train operation. This design not only enhances the riding comfort of passengers but also meets the environmental protection requirements of modern cities, reducing the noise impact on the surrounding environment. Through effective shock absorption and vibration control, the riding experience of passengers in urban rail transit is improved, and the noise and vibration impacts during train operation are reduced.

[0052] To further enhance the reliability of the system, the limit base (3) in this embodiment also integrates an anti-detachment function. It prevents accidents that may affect the safe operation of the train caused by the detachment of the rubber body. This design is applicable to urban rail transit trains, suitable for trains with high departure frequencies and high passenger flows. It can promote rail transit maintenance management and improve the overall operation efficiency. Since this anti-detachment type horizontal stop with adjustable performance can effectively disperse loads and vibrations, it reduces the wear and tear on the track and the vehicle, thereby extending the service life of the equipment and reducing the frequency of maintenance and replacement.

[0053] In summary, an anti-detachment type horizontal stop with adjustable performance in this embodiment, through the use of high-performance materials and acoustic optimization, solves the challenges in terms of safety, comfort, and economy in urban rail transit, and promotes the modernization and sustainable development of urban rail transit. This technical solution not only improves the overall operation efficiency of urban rail transit but also provides a safer and more comfortable travel experience for passengers.
